<h1 id="_1">概述</h1>
<h2 id="_2">总体概述</h2>
<p>太阳活动区非线性无力场3D数据集，使用改写Thomas Wiegelmann<code>wiegelmann(at)mps.mpg.de</code>的LINFF(An IDL-widget program for force-free coronal magnetic fields.)程序，2022年对第一批2010到2019年<a href="http://jsoc.stanford.edu/ajax/lookdata.html?ds=hmi.sharp_cea_720s">HMI活动区补丁矢量场数据</a>进行抽样预处理和计算。</p>
<p>整个处理流程如下：</p>
<p><img alt="workflow.drawio" src="assets/img/workflow.drawio.svg" /></p>
<p>HMI原始数据抽样细节将在<strong>原始数据及抽样</strong>部分进行介绍。程序改写内容包括，改写由IDL语言编写预处理等部分代码，需要配置自定义参数部分的代码，改写细节将在后面<strong>数据预处理及计算</strong>部分进行介绍。产品数据及使用方法可以在<strong>产品数据及使用</strong>和<strong>工具包</strong>部分查看；数据使用和合作申请详见<strong>数据支持</strong>，基于该数据库的相关成果和合作详见<strong>成果与引用</strong>。</p>
